DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings and in particular to FIGS. 1 and 2, a light-emitting building block according to the present invention comprises a hollow and light transmittable brick 10 and a plurality of electricity connection units 20 disposed in the brick 10. A control circuit board 11 is disposed in the brick 10. The brick 10 has a plurality of ring-shaped studs 12 projected from a top of the brick 10 and a plurality of tubes 13 defined in a bottom of the brick 10. The numbers, shapes, sizes and the positions of the tubes 13 are corresponding to the studs 12. A light member 14 is mounted on the control circuit board 11. A plurality of assembling holes 15 are defined through the control circuit board 11 and each assembling hole 15 is disposed between the stud 12 and the corresponding tube 13. According to the preferred embodiment, the brick 10 has a bottom base 102 and a top cover 101 mounted on the bottom base 102. The studs 12 and the tubes 13 are disposed on the top cover 101 and the bottom base 102, respectively.

As shown in FIGS. 3 and 4, the electricity connection unit 20 includes a hollow tubular member 30, two conducting members 40, a compression spring 50 and an annular electricity connection member 60. The tubular member 30 has a top end and a bottom end. Each of the top end and the bottom end of the tubular member 30 comprises a post 31, and each of the posts 31 includes a through hole 32 disposed at a center thereof. The post 31 disposed at the bottom end of the tubular member 30 is mounted on the control circuit board 11, and the posts 31 disposed at the top end and the bottom end of the tubular member 30 are respectively received in the stud 12 and the tube 13 of the brick 10. A side wall of the tubular member 30 comprises a side opening 33. The tubular member 30 includes two half tubes 34 connected with each other. One of the half tubes 34 has a male engaging member 35 and another half tube 34 has a female engaging member 36 corresponding to the male engaging member 35. After the male engaging member 35 is engaged with the female engaging member 36, the two half tubes 34 are assembled to form the tubular member 30. According to a first embodiment, a folding piece 37 is disposed between and connected with side edges of the two half tubes 34. The male engaging member 35 and the female engaging member 36 are respectively disposed at side edges opposite to the side edges connecting with the folding piece 37. The male engaging member 35 and the female engaging member 36 include an engaging rod 351 and an engaging hole 361, respectively. Therefore, after the folding piece 37 is folded, the engaging rod 351 of the male engaging member 35 is engaged with the engaging hole 361 of the female engaging member 36 to assemble the two half tubes 34 together. Referring to FIG. 5, each half tube 34 according to a second embodiment includes a male engaging member 35 and a female engaging member 36 disposed at two opposite side edges thereof. The male engaging member 35 and the female engaging member 36 disposed on one half tube 34 are corresponding to the female engaging member 36 and the male engaging member 35 disposed on another half tube 34, respectively. Therefore, when assembling the tubular member 30, the two half tubes 34 are facing with each other and the male engaging member 35 and the female engaging member 36 disposed on one half tube 34 are respectively engaged with the female engaging member 36 and the male engaging member 35 disposed on another half tube 34.

The two conducting members 40 are received in the top end and the bottom end of the tubular member 30, respectively. Each conducting member 40 extends through the through hole 32 and projects out of the tubular member 30. Portions of the conducting members 40 projecting out of the top end and bottom end of the tubular member 30 are received in the stud 12 and the tube 13, respectively. The conducting member 40 comprises a head 41 and a tail 42. The head 41 of the conducting member 40 has a diameter larger than that of the through hole 32 and is received in the tubular member 30. The tail 42 has a diameter smaller than that of the through hole 32, and extends through the through hole 32 and projects out of the tubular member 30.

The compression spring 50 is vertically received in the tubular member 30. Both ends of the compression spring 50 are pressed against the heads of the two conducting member 40, thereby forcing the tails 42 to project out of the tubular member 30. The spring 50 has a first wire 51 which passes through the side opening 33 of the tubular member 30 and connects with the control circuit board 11.

The annular electricity connection member 60 is sleeved on the top end of the tubular member 30, so that the annular electricity connection member 60 encircles the post 31 of the tubular member 30 and is received in an inside of the stud 12. The annular electricity connection member 60 includes a second wire 61 extends along the side wall of the tubular member 30. The second wire 61 has a length long enough to pass through the control circuit board 11 and includes a bending portion 62 disposed by the inner surface of the tube 13. A lower end of the second wire 61 is connected with the control circuit board 11. According to the preferred embodiment, the annular electricity connection member 60 is a conical spring.

Referring to FIG. 6, when the brick 10 is connected with another brick 10, the studs 12 of one brick 10 are engaged with the tubes 13 of another brick 10. The conducting members 40 disposed in the studs 12 of one brick 10 are contacted with the conducting members 40 disposed in the tubes 13 of the corresponding brick 10. The first wire 51 is connected with the control circuit board 11 and the compression spring 50. Thus, after the multiple bricks 10 are assembled together, the control circuit boards 11 disposed in the bricks 10 are electrically connected with each other by the first wires 51, the compression springs 50 and the conducting members 40. Moreover, the bending portion 62 of the annular electricity connection member 60 is disposed by the inner surface of the tube 13. Therefore, after the studs 12 are engaged with the tubes 13, the bending portions 62 are inserted into the studs 12 and contacted with the annular electricity connection members 60 that are disposed by inner surfaces of the studs 12. The second wires 61, which are connected with the control circuit boards 11 of the bricks 10, are electrically connected with each other by the annular electricity connection members 60 and the bending portions 62. Thus, the control circuit boards 11 are electrically connected in parallel by the first wires 51 and the second wires 61. When any one of the electricity connection units 20 (including the first wire 51 and the second wire 61) is connected with the power source, the control circuit boards 11 are powered and the light members 14 are turned on to provide the interlocking bricks 10 with the visual attraction.
